Patented Nov.VV 24, `1931v This inventionrelates toan expansion pipe joint tting and Aespecially to joints ofsoil and vent pipes for plumbingstands or stacks in buildings:

i" 5'fBnildingconstruction at' the present time i frequently requires that lthel plumbing pipe V'staclfs be installed Vahead oithe installation of tliepermanentliiooring necessitating in fa ltemporarily ysupportingf of the-pipe stacks until suchntime as the permanent looringis V'putinpla-ze It is necessary in su'chinstalla-y tions; therefore; to 'provide expansion' joints atvarious places in pipe stacks so that When thestacks are putin use, the range ottem-` peratures ot' the Waste Water and the like will cause lexpansion and contraction of theV pipe',-

and Will prevent buckling of thepipe and cracking of the caulking material.

An object of this invention is to provide a itting for providing expansion joints in pipe stacks to temporarily support the stacks Withthe various pipe connections and fittings spaced in such manner to allow for expansion t and contractionV Whenin use.

Another object of the inventionis to provide a iitting for temporarily'spacing adj a cent pipes in pipe stacks during construction of the building which fitting may be removed after-the pipe stack has beensecured permanently in position. A further object of the invention is to provide a fitting for external application to certain of the pipe members in' a pipe stack for desired places p providing expansion joints at in the stack.

The above, other and furtherobjects .of the invention Will be apparent from the following description, accompanying drawings and appended claims.

An embodiment of the invention is illustrated in the accompanying drawingsvand the views thereof are as follows:
